Section 24 USB 2.0 Host/Function Module (USB)
The USB 2.0 host/function module (USB) is a USB controller, which provides capabilities as a
USB host controller and USB function controller function.
When used as the host controller, this module supports high-speed transfer defined by USB
(universal serial bus) Specification 2.0, full-speed transfer, and low-speed transfer, allowing the
use of two USB ports.
When used as the function controller, this module supports high-speed transfer defined by USB
Specification 2.0, and full-speed transfer, allowing the use of one USB port.
This module has a USB transceiver* and supports all of the transfer types defined by the USB
specification.
This module has a 10-Kbyte buffer memory for data transfer, providing a maximum of ten pipes.
Any endpoint numbers can be assigned to PIPE1 to PIPE9, based on the function devices or user
system for communication.
Note: * When this module is to be used, start by making settings for the internal USB
transceiver. For details, see section 24.5.1, Procedure for Setting the USB Transceiver.
24.1 Features
(1) Host Controller and Function Controller Supporting USB High-Speed Operation
• The USB host controller and USB function controller are incorporated.
• The USB host controller and USB function controller can be switched by register settings.
• Both high-speed transfer (480 Mbps) and full-speed transfer (12 Mbps) are supported.
• High-speed/full-speed/low-speed USB transceiver (shared by the USB host and USB function)
is incorporated.
(2) Reduced Number of External Pins and Space-Saving Installation
• On-chip D+ pull-up resistor (during USB function operation)
• On-chip D+ and D- pull-down resistor (during USB host operation)
• On-chip D+ and D- terminal resistor (during high-speed operation)
• On-chip D+ and D- output resistor (during low-speed/full-speed operation)
